Diffuse Versus Non-Diffuse Energy and the Effect of Acoustic Diffusors

This paper discusses the effect of diffusers on the diffuse and nondiffuse sound energy in a room. The paper first defines diffuse versus nondiffuse energy, then presents a simple means of measuring it. It also discusses the effect of diffusers on the diffuse energy using a simple theoretical model. The paper presents simulations on an electromagnetic scale model of a reverberant room which show the beneficial effect of diffusers on diffuse versus nondiffuse energy ratio.
